Best test to access the fluid status in a burn patient is

Correct Answer: B

Rationale: Fluid status in burn patients is critical due to massive losses from damaged skin. Electrolyte levels (choice A) indicate imbalances but not volume status directly. Hematocrit (choice B) measures blood concentration; in burns, it rises with hemoconcentration from plasma loss, making it a practical indicator of fluid shifts. Creatinine level (choice C) assesses kidney function, indirectly reflecting hydration over time, not acutely. Hemoglobin level (choice D) tracks oxygen-carrying capacity but is less sensitive to immediate fluid changes. B is correct, as hematocrit provides a rapid, reliable gauge of fluid resuscitation needs. Nurses use this, alongside urine output, to titrate IV fluids, preventing shock or overload in burn management.

Correct Answer: C

Rationale: An antibody-antigen reaction from a microorganism infection, like bacterial invasion, typically produces purulent exudates (C), rich in pus, neutrophils, and debris due to active immune response. Serous exudates (A) are clear and watery, seen in mild inflammation (e.g., blisters). Serosanguinous (B) is a mix of serum and blood, common in surgical wounds. Sanguinous (D) is bloody, linked to trauma or vessel damage, not infection-driven immunity. Purulent exudates reflect the body's fight against pathogens, as neutrophils engulf microbes, forming pus a hallmark of such reactions making C the accurate choice.

Correct Answer: D

Rationale: Martina is in a crisis (D). Her devastation, depression, and crying after losing at Wimbledon suggest a sudden, overwhelming event disrupting her homeostasis, fitting crisis definition. Stress (A) is too mild; anxiety (B) lacks the depth of her response. Exhaustion in GAS (C) follows prolonged stress, but this is acute. Crisis involves intense emotional distress from a specific trigger, like career setback, making D correct.

Correct Answer: C

Rationale: Legrande uses displacement (C), redirecting anger from his arrest to his son. Restitution (A) repairs damage (e.g., gifts). Projection (B) attributes feelings to others. Undoing (D) reverses actions. Displacement, per Freud, shifts emotions to a safer target, fitting Legrande's outburst, making C correct.

Correct Answer: C

Rationale: Refused betaxolol' (C) violates good recording; it lacks why or follow-up, per standards (e.g., completeness). A, B, D are specific and clear. C's brevity omits context, making it the violation.
